Let's start with a review. An American buyer spent $36.99 on a pair of AI real-time translation earbuds, and after using them, left exactly one line in the review section:
"these are just earbuds they do not translate anything do not buy"
Don't laugh just yet, because that one line basically pulls the pants off the entire translation earbud category β "real-time translation" is the loudest selling point in every listing, and at the same time the feature users complain about the most. One feature holding both titles at once, that's rare.
Where the Data Came From
We ran a full review analysis on two translation earbuds listed on Amazon using our own competitor analysis tool. The window runs from August 2024 to August 2026, 25 months, 522 verified purchase reviews in total.
The two products we picked are both representative in their own way. One is a translation earbud from Csasan, $39.99, listing promises 165 languages with subscription-free translation β the grinder of the white-label crowd. The other is the Soundcore P31i from Anker, $36.99 β and nobody in cross-border e-commerce needs an introduction to that brand.
Overall market picture: average rating 3.9, negative review rate 14.6%. Sounds passable at first glance, but once you break it down you realize this number hides more than it tells.

70% of Translation Earbud Buyers Never Use the Translation
This was the most counter-intuitive finding in the whole dataset, and honestly it caught us off guard too.
On the Csasan side, 75% of buyers use the earbuds for music, podcasts and daily commuting, only a quarter actually use the translation feature. Soundcore is about the same, 70% listen to music and take calls, 30% bought it specifically for the AI translation.
In other words, this category sells "translation" on the surface but mostly delivers a decent-sounding pair of Bluetooth earbuds. The translation feature is more like a marketing hook β that one line of "AI real-time translation" on the listing pulls people in, they pay, and then most of them quietly go listen to music.
The people who actually care about translation? They're the main source of the negative reviews. On Csasan, "poor translation accuracy" and "app fails to connect to earbuds" are tied for the top pain point, each taking a third of all complaints. One buyer's words are pretty typical: "I bought it because it said real-time translation, and it's not" β and by the way, this person's earbuds were charged all night, then showed low battery right after unplugging. Already wants a refund.
Big Brands Faceplant Too, and Uglier
A lot of sellers think like this: white labels are unreliable, just follow the big brands. This dataset slaps that idea right across the face.
The Soundcore P31i rates 3.8, half a star below Csasan's 4.3, with a 15.4% negative rate β fifty percent worse than the white label. A product backed by Anker's brand equity scored a 2 out of 10 on wearing comfort, the lowest dimension score in the entire report.
Its number one complaint isn't translation, it's that the earbuds won't stay in. "No matter what ear tips i use, they just fall out of my ears" β this reviewer admits the sound quality is actually good, but "that doesn't matter when they just fall out."
Number two is even more absurd: the touch controls are too sensitive. When the buds keep slipping you're constantly adjusting them, and every touch triggers something β switching noise cancellation modes, pausing playback, and worst of all, the call hang-up gesture can't be disabled. Another reviewer wrote a long paragraph about how every adjustment might trigger god-knows-what, "terribly annoying", and closed with "i am not a loyal soundcore customer anymore. i got really disappointed... i will explore other brands from now on."
That one review does more damage than ten ordinary negative reviews. A brand spends a decade-plus building trust, and one non-disableable hang-up gesture burns it down. And the trend is still deteriorating β May 2026 alone hit a 33.3% negative rate for the P31i, the trailing three-month average is 12.8%, and the report's verdict is four words: getting worse.
The Biggest Lie: The Subscription Fee That Isn't on the Page
Back to the title. What is the biggest lie in this market?
The Soundcore P31i advertises its translation feature, but doesn't tell you it's free for a limited time only β once the trial ends, you need a paid subscription. Our report calls this an "undisclosed subscription requirement." Users call it getting scammed.
That 30% who bought specifically for translation discover the monthly fee after a while, and the frustration lands directly on the ratings. Meanwhile on the other side, Csasan markets "no subscription" as its core selling point, which genuinely attracts people β but then the translation itself doesn't work well, and the promise falls through again.
So there you have it: one side is free but broken, the other works a bit better but hides a fee. The whole category is fudging on the "real-time translation" promise, the only difference is how they crash.
After going through all 527 reviews, our most confident conclusion is this: demand for translation earbuds is real β the P31i pulled in 114 reviews in August 2026 alone, the heat is visible β but the execution is failing across the board.
What This Means for Sellers: The Bar Is Lower Than You Think
There's a passage in the report we'll quote as-is:
"Reliability is the unmet need. Neither competitor delivers out-of-the-box reliable translation. A new entrant that prioritizes seamless app-to-earbud connection, accurate voice recognition, and transparent feature access will immediately stand out. The bar is low, and clearing it is entirely feasible."
Translated into plain language: if your translation actually works, your app actually connects, and your pricing is honest, you've already beaten both of these players. Sounds like a joke, but that's what the data says.
Let's do the math for sellers in this category. Assume 1,000 units a month. Based on the P31i's complaint structure, returns alone are estimated to cost $2,885 a month, $35K a year β and that's the conservative floor, since way more people return than leave reviews. What are the top two return reasons? Poor fit and Bluetooth drops. Neither is rocket science: a few more ear tip sizes, tune the antenna properly, and that money stays in your pocket.
Csasan's numbers are worth a look too: estimated $1,280 monthly loss from returns, with 71.4% of return mentions tied to connection problems. One app's connection stability decides a third of all returns in this category. Let that sink in.
Final Words
When doing product research, everyone stares at ratings and BSR rankings. But break 527 reviews apart and you'll see that a 3.9-rated market hides both big traps in niche use cases and the opportunity to stand out by simply getting connectivity and pricing transparency right. You won't see any of this by staring at listings.
The data in this article comes from a Choicesages.com Amazon competitor analysis report β enter your competitor's ASINs, and it automatically pulls the full review history, clusters pain points, estimates return losses, and generates an action list for product and ops. Whether you're doing translation earbuds or any other category, run a free report on your own competitors β frankly, your competitor's negative reviews are where your opportunity hides. All the talk in the world isn't worth running one yourself.
